I was having a power issue and when I run anything through the on-board voltage regulator (on a linksprite redback), either filtered 5v using a voltage regulator and capacitors before connecting to the redback, or 7.4v unregulated connected directly to the redback it is knocking the power to the 5v output pin to ~3.03v. The range finders I am running are based on a 5v set up.When I run the board through the USB cable I have no problem with the sensors. Can I put regulated 5v power on the USB VCC input pin and ground on the USB header?Would doing this solve my problem as well? I tested voltages with the USB cable connected and it is doing just over 4.6v, would connecting 5.02v be a problem?I haven't tried simply because I already burnt out a ~$60 board and had to replace it with ~$80 and I don't want to have to spend more money on credit to finish this project HAHA!This is a picture, the redback is a copy of the asynclabs yellowjacket. I can see the lines from the VCC go to the 5v output pin, but it also goes to the ttl converter, would that create a problem?http://asynclabs.com/wiki/images/8/8c/YellowJacketv1.JPGThanks for any help,Postholes
